Rosacea is a chronic inflammatory skin condition that causes facial redness, flushing, visible blood vessels, and sometimes small red bumps or pus-filled pimples, most commonly across the cheeks, nose, chin, and forehead. It typically develops in adults over 30, is more commonly diagnosed in people with fair skin, and tends to flare in cycles rather than staying constant, often triggered by specific, individual factors like sun exposure, heat, spicy food, or alcohol. There’s no cure for rosacea, but most people can significantly reduce flares and manage symptoms with consistent skincare, trigger avoidance, and, when needed, prescription treatment.
This guide covers the different types of rosacea, what causes flares, how it’s diagnosed, and the treatment options — from topical medications to laser therapy — that dermatologists actually use.
What Is Rosacea?
Rosacea is a chronic condition involving abnormal blood vessel behavior and inflammation in the skin, though its exact underlying cause isn’t fully understood. It’s not caused by poor hygiene and isn’t contagious. Because early rosacea can look similar to acne, sunburn, or general skin sensitivity, it’s commonly under-recognized in its earlier stages, and symptoms tend to worsen gradually over time without management.
Common Rosacea Symptoms
- Facial redness that comes and goes, often across the cheeks and nose
- Flushing that’s more intense or longer-lasting than typical blushing
- Visible blood vessels (telangiectasia) on the face
- Small red bumps or pus-filled pimples, which can resemble acne but occur without blackheads
- Skin sensitivity, including stinging, burning, or a feeling of tightness
- Thickened skin, particularly around the nose, in more advanced, less common cases
- Eye irritation (ocular rosacea), including dryness, redness, or a gritty feeling
Types of Rosacea
- Erythematotelangiectatic rosacea — persistent redness and flushing, with visible blood vessels
- Papulopustular rosacea — redness combined with acne-like bumps and pimples
- Phymatous rosacea — thickened, bumpy skin texture, most often affecting the nose (rhinophyma), more common in men
- Ocular rosacea — affects the eyes and eyelids, causing dryness, irritation, redness, and sometimes swollen eyelids
Many people experience overlapping features of more than one type rather than a single, isolated form.
What Causes Rosacea?
The exact cause isn’t fully understood, but researchers believe it involves a combination of factors: abnormal blood vessel reactivity, which causes exaggerated flushing and persistent visible vessels, immune system involvement, including an overactive inflammatory response in the skin, genetics, since rosacea often runs in families, particularly among people with fair skin and Northern or Eastern European ancestry, and Demodex mites, a microscopic organism naturally present on skin that appears in higher numbers on rosacea-affected skin, though its exact causal role is still being studied.
Common Rosacea Triggers
Triggers don’t cause rosacea itself but commonly set off flares in people who already have it, and they vary meaningfully between individuals. Frequently reported triggers include sun exposure, one of the most consistently reported triggers, heat and hot weather, including hot showers and saunas, spicy foods, alcohol, particularly red wine, hot beverages, stress and strong emotions, intense exercise, and certain skincare ingredients, such as alcohol, fragrance, and harsh exfoliants. Keeping a trigger diary can help identify which specific factors matter most for an individual.
How Is Rosacea Diagnosed?
Rosacea is diagnosed through a physical exam and a review of symptom history and patterns, since there’s no specific blood test or biopsy required in typical cases. A dermatologist will typically rule out other conditions that can look similar, including acne, lupus, and allergic reactions, before confirming a rosacea diagnosis and determining which subtype is present.
Rosacea Treatment Options
- Topical metronidazole or azelaic acid, commonly prescribed first-line treatments for reducing redness and bumps
- Topical ivermectin, which also addresses Demodex mite overgrowth associated with rosacea
- Oral antibiotics (typically low-dose doxycycline), used at anti-inflammatory rather than antibacterial doses for moderate-to-severe cases
- Topical brimonidine or oxymetazoline, which temporarily constrict blood vessels to reduce visible redness for several hours at a time
- Laser and light therapy (such as pulsed dye laser or IPL), effective for treating visible blood vessels and persistent redness that doesn’t respond to topical treatment
- Isotretinoin, occasionally used in low doses for severe, treatment-resistant papulopustular rosacea
- Prescription eye drops or oral antibiotics, for ocular rosacea, managed alongside an ophthalmologist when needed
Skincare Tips for Rosacea-Prone Skin
- Use a gentle, fragrance-free cleanser and avoid scrubbing or hot water
- Apply broad-spectrum mineral sunscreen daily, since sun exposure is one of the most common triggers; see our sunscreen guide for choosing a well-tolerated formula
- Choose calming, barrier-supporting ingredients like niacinamide, and avoid alcohol-based or heavily fragranced products
- Introduce any new product gradually and patch test first, since rosacea-prone skin reacts easily
- Track personal triggers and adjust diet, environment, or habits accordingly rather than assuming universal triggers apply
Frequently Asked Questions
Can rosacea be cured?
There’s currently no cure for rosacea, but most people can control symptoms well and reduce flare frequency with consistent treatment, trigger avoidance, and appropriate skincare.
What is the difference between rosacea and acne?
Rosacea typically involves persistent facial redness, flushing, and visible blood vessels alongside any bumps, and it doesn’t produce blackheads, while acne is centered on clogged pores, blackheads, and whiteheads without the same background redness and flushing pattern.
What foods should you avoid with rosacea?
Common dietary triggers include spicy foods, alcohol (especially red wine), and hot beverages, though triggers vary significantly by individual, so tracking personal patterns is more useful than following a universal avoidance list.
Is rosacea caused by poor hygiene?
No, rosacea is not caused by poor hygiene or an infection in the traditional sense, and it isn’t contagious. It’s related to blood vessel reactivity, immune response, and genetic factors.
Can rosacea affect the eyes?
Yes, ocular rosacea affects the eyes and eyelids, causing dryness, redness, irritation, and sometimes swollen eyelids, and it can occur alongside or occasionally before the facial skin symptoms typically associated with rosacea.
Does rosacea get worse with age?
Without management, rosacea often gradually worsens over time, and some features, like visible blood vessels or skin thickening, tend to become more prominent with prolonged, untreated flares, which is part of why earlier treatment is generally recommended.
Can stress trigger a rosacea flare?
Yes, stress and strong emotional reactions are commonly reported rosacea triggers, likely related to their effect on blood vessel reactivity and inflammation.
